I got my equipment pad hooked up on Saturday, 5/1/21. Under the cover (with a flashlight) our water is crystal clear, with very minor debris on the bottom. I'm not ready to open yet, but wanted to get some chlorine into the water before water temp rises above 50 degrees. Solid winter cover remains on. Set the pump to recirculate and fired it up. Initial tests: CL-0, pH-7.4, TA-80, CYA-40 CH-125. Water temp 48 degrees. Our liquid chlorine is manually dosed. I felt I was probably not going to have to SLAM, but added an elevated dose of chlorine to bring it up to a level of 10-12, just as a precaution. After several hours of water circulation, my tests were as follows:
5/1/21 FC-11.5 CC-0.5 pH-7.4 TA-90 CYA-40 CH-125 Temp 48 degrees.
I began filtering today, after several hours of recirculating yesterday. Today's tests after four hours of filtering:
5/3/21 FC-10.5 CC-0.5 pH-8.2 TA-110 CYA-40 CH-125 Temp 52 degrees.
What made my pH and TA go up? Should I make an adjustment or just continue to monitor it? We don't plan to open for a couple weeks or so.
Thanks!
